OVERTAKING MANEUVERS THAT THREATEN ROAD SAFETY: Prohibitions

Article 87. Prohibitions.
1. It is prohibited to overtake:
a) On bends and gradients with reduced visibility and in general, any place or circumstance where visibility is insufficient to overtake or abort the maneuver once started, unless both traffic flows are clearly delimited and the maneuver can take place without invading the area reserved for oncoming traffic (LST Art 36,1).
In accordance with the arrangements in the previous paragraph, it is prohibited, in particular, to overtake another vehicle that is overtaking when the caracteristics of the vehicle in front obstructs forward visibility.
b) At signed pedestrian crossings, at intersections with cyclist routes, at level crossings and their approaches (LST Art 36,2).
However, this prohibition is not applicable when overtaking two wheeled vehicles that by their reduced dimensions do not obstruct lateral visibility, at a level crossing or its approaches, provided overtaking is so indicated by horn or lights. The prohibition at a signed pedestrian crossing is not applicable either if overtaking is done at a speed sufficiently reduced that it allows time to stop if danger of running over occurs.
c) At intersections and their approaches, except when:
i) At a circular intersection or roundabout.
ii) Overtaking on the right, as described in Article 82.2.
iii) The road has priority at the intersection and is expressly signalled as such.
iv) Overtaking two wheeled vehicles (LST Art 36,3).
d) In tunnels, underpasses and sections of road governed by the signal "Tunnel" (S-5) in which there is only one lane in each direction.
2. Infractions of this Article are considered serious offences (LST Art 65.4.c).
